Pretty typical of the runout on those pencil grinders, the collets aren't very precision.
A careful whack and a diamond truing of the wheel will help out a lot to get a good finish.
I've done similar grinding by just putting the grinder in the toolpost directly. and carefully tightening the setscrews down on the grinder body.
Not precision grinding just a gotta get it done job.
Good job.
I use the same type of grinder in a boring bar holder, sleeved to suit the diameter of the body, for sharpening end mills in the lathe.
When I was young and poor I learnt a trade, and after many years of hard work I’m not young anymore.
